Abstract
Transluminal in vitro resection of severely calcified human aortic valves has already been successfully carried out by our group. The aim of this study was to analyze endovascular laser-assisted resection of human aortic valves in situ in 10 human cadavers.

After deployment and sealing of the chamber, stable function with a continuous chamber lavage of 1.58 L/min saline solution was established (8/10 cases). The endoscopically guided laser fiber was delivered via the right carotid artery. After fixation of a leaflet by a forceps catheter, the native leaflets were resected each by a thulium:YAG laser with 20-W power rating. Macropathology and micropathology of surrounding anatomic structures were analyzed.</AbstractText><AbstractText Label="RESULTS" NlmCategory="RESULTS">The duration of transluminal positioning and deployment of the aortic valve isolation chamber took 7.3 +/- 5.8 minutes. Fluoroscopy confirmed sealed chambers. The resection was completed in all leaflets and took, on average, 6.0 +/- 3.5 minutes per leaflet. The aortic wall was moderately injured in 4 of 10 cases and the aortic annulus in two cases with one aortic wall perforation. The surrounding tissue, the coronary ostia, the mitral valve, and the left ventricular outflow tract remained unaffected.</AbstractText><AbstractText Label="CONCLUSION" NlmCategory="CONCLUSIONS">This study demonstrates the feasibility of endovascular resection of human aortic valves in situ. This is a subsequent step toward complete percutaneous replacement (resection and implantation) of human aortic valves.</AbstractText></Abstract><AuthorList CompleteYN="Y"><Author ValidYN="Y"><LastName>Quaden</LastName><ForeName>René</ForeName><Initials>R</Initials><AffiliationInfo><Affiliation>Department of Cardiovascular Surgery, University Hospital Schleswig-Holstein, Campus Kiel, Kiel, Germany.</Affiliation></AffiliationInfo></Author><Author ValidYN="Y"><LastName>Attmann</LastName><ForeName>Tim</ForeName><Initials>T</Initials></Author><Author ValidYN="Y"><LastName>Schünke</LastName><ForeName>Michael</ForeName><Initials>M</Initials></Author><Author ValidYN="Y"><LastName>Theisen-Kunde</LastName><ForeName>Dirk</ForeName><Initials>D</Initials></Author><Author ValidYN="Y"><LastName>Cremer</LastName><ForeName>Jochen</ForeName><Initials>J</Initials></Author><Author ValidYN="Y"><LastName>Lutter</LastName><ForeName>Georg</ForeName><Initials>G</Initials></Author></AuthorList><Language>eng</Language><PublicationTypeList><PublicationType UI="D016428">Journal Article</PublicationType><PublicationType UI="D013485">Research Support, Non-U.S. Gov't</PublicationType></PublicationTypeList></Article><MedlineJournalInfo><Country>United States</Country><MedlineTA>J Thorac Cardiovasc Surg</MedlineTA><NlmUniqueID>0376343</NlmUniqueID><ISSNLinking>0022-5223</ISSNLinking></MedlineJournalInfo><CitationSubset>AIM</CitationSubset><CitationSubset>IM</CitationSubset><MeshHeadingList><MeshHeading><DescriptorName MajorTopicYN="N" UI="D001021">Aortic Valve</DescriptorName><QualifierName MajorTopicYN="Y" UI="Q000601">surgery</QualifierName></MeshHeading><MeshHeading><DescriptorName MajorTopicYN="N" UI="D002102">Cadaver</DescriptorName></MeshHeading><MeshHeading><DescriptorName MajorTopicYN="N" UI="D002114">Calcinosis</DescriptorName><QualifierName MajorTopicYN="Y" UI="Q000601">surgery</QualifierName></MeshHeading><MeshHeading><DescriptorName MajorTopicYN="Y" UI="D004724">Endoscopy</DescriptorName></MeshHeading><MeshHeading><DescriptorName MajorTopicYN="N" UI="D005240">Feasibility Studies</DescriptorName></MeshHeading><MeshHeading><DescriptorName MajorTopicYN="N" UI="D006349">Heart Valve Diseases</DescriptorName><QualifierName MajorTopicYN="Y" UI="Q000601">surgery</QualifierName></MeshHeading><MeshHeading><DescriptorName MajorTopicYN="N" UI="D006801">Humans</DescriptorName></MeshHeading><MeshHeading><DescriptorName MajorTopicYN="N" UI="D053685">Laser Therapy</DescriptorName></MeshHeading></MeshHeadingList></MedlineCitation><PubmedData><History><PubMedPubDate PubStatus="received"><Year>2007</Year><Month>5</Month><Day>28</Day></PubMedPubDate><PubMedPubDate PubStatus="revised"><Year>2007</Year><Month>8</Month><Day>28</Day></PubMedPubDate><PubMedPubDate PubStatus="accepted"><Year>2007</Year><Month>11</Month><Day>26</Day></PubMedPubDate><PubMedPubDate PubStatus="pubmed"><Year>2008</Year><Month>5</Month><Day>6</Day><Hour>9</Hour><Minute>0</Minute></PubMedPubDate><PubMedPubDate PubStatus="medline"><Year>2008</Year><Month>6</Month><Day>5</Day><Hour>9</Hour><Minute>0</Minute></PubMedPubDate><PubMedPubDate PubStatus="entrez"><Year>2008</Year><Month>5</Month><Day>6</Day><Hour>9</Hour><Minute>0</Minute></PubMedPubDate></History><PublicationStatus>ppublish</PublicationStatus><ArticleIdList><ArticleId IdType="pii">S0022-5223(07)01962-9</ArticleId><ArticleId IdType="doi">10.1016/j.jtcvs.2007.11.036</ArticleId><ArticleId IdType="pubmed">18455588</ArticleId></ArticleIdList></PubmedData></pubmed></record>Pour manipuler ce document sous Unix (Dilib)
